In vitro transfer of R factors in sterilized fish culturing pondwater was observed from the strains of Escherichia coli K-12, CSH-2 (R+) and Enterobacter cloacae 0-20 to the strain of Aeromonas liquefaciens Y61 SMγ (R-) but was not observed from A. liqufeacinns A-17 and 8L2 to E coli CSH-2 (R-). The sterilized pond water supported the growth of these bacteria. In vivo transfer of R factors in the intestinal tracts of carp from E. coli CSH-2 (R+) to A. liquefaciens Y62 SMγ (R-) were hardly observed.
